Condemning the gang rape of a 23-year-old girl in the capital, Bollywood star Salman Khan Tuesday said rapists should be hanged. "In my view, there should be a death sentence for all rapists. Such things have no role in our life. I feel disgusted after hearing such things. For me, this is a third grade crime. I also believe that there should be a norm that if a rapist goes to jail, he should be beaten till death," said the 46-year-old.
